No such thing as approval (unless using Steemit as part of the name, and also unless you mean reception instead of approval). Its all voluntary. You just have to build it yourself, or have people interested enough to spend time on it. A prototype / mockup would do better. But in the end iit comes down to this - would you spend time contributing this with no guarantees of immediate community reception? If not, then best to move on. Or try to get in touch with some devs who might be interested.
